Need help on 10 what do I do with the fraction in parentheses

You should multiply it by the number beside it, four.

Step-by-step explanation:

You may or may not know this depending on how new to this you are but you always do the parenthesis first, it's the first rule of pemdas.

1/4 x 4 would result in 1.

multiply the 4 by the 1 and get 4/4 reduced to 1

hope this helps :D

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
